在没有查找字段的情况下检索APIView? [英] RetrieveAPIView without lookup field?

问题描述

默认情况下 RetrieveAPIView 或 RetrieveUpdateAPIView 需要 lookup_field 来检索模型.

By default RetrieveAPIView or RetrieveUpdateAPIView requires lookup_field to retrieve Model.

但是在我的情况下，我想通过 self.request.user 检索我的模型.

However in my case, I want to retrieve my model by self.request.user.

这是 views.py 示例

Here is views.py example

class ProfileRetrieveAndUpdateProfile(generics.RetrieveUpdateAPIView):
    queryset = Profile.objects.all()
    serializer_class = ProfileRetrieveAndUpdateSerializer
    lookup_field = 'user_id'

    def get_queryset(self):
        qs = Profile.objects.all()
        logged_in_user_profile = qs.filter(user=self.request.user)
        return logged_in_user_profile

我可以在没有 lookup_field 的情况下使用 RetrieveAPIView 吗?

Can I use RetrieveAPIView without lookup_field?

推荐答案

您需要覆盖 get_object

def get_object(self):
  queryset = self.get_queryset()
  obj = get_object_or_404(queryset, user=self.request.user)
  return obj
